To al?, whom man concern:

l Be it known that I, ROBERT J. MINER, of Grcenwich,rcounty of Fairfield, State of Connecticut, have invented certain new and useful Improvements in Starting-Torches for Gaseous-Fuel Burners, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates particularly to that class of starting-torches which is used for heating the vaporiZing-coil or generator in the main burner of automobiles, whether using gasolene or kerosene; but the construction may be used for other purposes where a starting-torch is required.

, The object of the invention is to furnish improvements in the torch whereby it may be economically constructed, the jet-aperture readily cleaned, the coil furnished with aprimary heater, which when desired may be supplied continuously with an inflammable,7 so as to maintain the vaporization in the torchcoil when started, and to protect the flame of the primary heater, and the torch protected from extinguishment by wind.

These objects are accomplished by the means shown in the annexed drawings, in which- Figure l is a side view of a torch with part of a main burner in section. Fig. 2 shows the torch with the casing, the porous pad, and the lamp-wick in section. Fig. 3 is a plan, partly in section, of the smaller end of the coil and the jet-pipe. Fig. 4 shows the larger end of the coil; Fig. 5, a cross-section of the coils 'b and b at the point where the letter b' is applied to the outer coils in Fig. 2, and Fig. 6 the inner end of the coil.

A designates the bed of the torch supporting the porous pad B and the torch-coil, which is preferably formed of a single piece of steel tubing, the coils of which are supported by the feed-pipe a. The torch-pipe is formed with an inner coil the inner end c of which is bent at right angles to the coil and is formed with jet-aperture d opposite the center of the coil to discharge a jet of vapor therein. The tube is shown extended in astraight line beyond the jet-aperture sufficiently to receive a screw-plug f, which permits the interior of the tube at the jet to be readily cleaned. The outer end of the coil b is rellexed and wound into several larger encircling coils 7)',

the end of which extends along beneath the coil and connects with the feed-pipe a. The jet discharged from the aperturecl is ig- 'nited and expands rapidlyas it moves forward through the coil Z), and the enlarged coils are provided to intercept the expanded portion of the flame and utilize the heat thereof near the forward end of the coil b, so as to warm the oil which is supplied to the larger coils by the feedpipe c. The oil passes from such larger coils into the small coil I) and is vaporized in its passage to the jet-aperture el, such vaporization being very rapid and perfect, owing to the heating of the oil in the larger coils H.

A casing C is fixed removably upon the bed A and the feed-pipe a is supported in the rear end of the casing, and thus sustains the coils above the pad B. The casing is constructed with closed top, bottom, sides, and outer end and open only upon the inner end where the llame is discharged against the vaporizingtube of the vapor-burner. The sides of the casing have perforations D, which supply air for the combustion of the vapor-jet. An aperture is shown extending through the bed and the pad for a tubular receptacle g, which is supplied with oil by a feed-pipe /t and contains a wick it', located beneath the feed-pipe a and the coil The feed-pipes a and L are extended to an oil-tank E, which is shown in diagrammatic form only, and cocks a and j are supplied, respectively, to these pipes to cut olf the flow of oil from the tank.

In Fig. l the edge of a vapor-burner is shown, partly in section, of the kind used under steam-boilers in automobiles, the VaporiZ'ing-pipe F of the burner G being in a vline with the axis of the torch-coils, so that the jet of flame may be projected against such pipe. The bed A is shown secured byflange A to the side of the vapor-burner G, and the torch thus operates to heat the vaporizer F either while starting the main burner or during the operation.

The wick it or pad B forms a primary heater for the torch-coils, and the llame of such primary heater vis very liable to be extinguished by wind, and difficulty in starting the burner has heretofore been frequently experienced from this cause,

The casing C operates in my construction to wholly inclose the primary heater and the IOO torch, and thus protects them from drafts which might extinguish the primary heater or the flame of the torch.

The operation of the apparatus is as follows: The torch-coils are first heated by pouring a charge of combustible, as alcohol or oil,

upon the porous pad B, which is preferaltyVv A izing-tube F of the burner under the boiler.

When the use of a boiler is suspended temporarily, as is common when an automobile is left standing, the torch-coil may be kept hot (although the oil-feed to the torch be cut OH by closing the cock c) by opening the cock j and supplying oil to thewick z. Such heating of the torch-coil enables it to immediately vaporize oil when it is desired to again start up the boiler, as the opening of the cock rt produces vaporization of oil in the torch and immediately commences the heating of the vaporizing-tube F of the burner under the boiler. If desired, the wick t may be supplied with alcohol instead of oil by a tank separate from the tank which supplies the oil to the torch, and thus avoid the deposition of soot upon the coils b and b.

My invention diers from others in having the vaporizing-coil of the torch constructed with an inner coil, an outer coil connected to one end of the same and extended backwardly over the inner coil, and the pipe then extended along the lower side of the coil, so as to be heated simultaneously with the coil by a primary heater, and it also differs in having a bed-plate to support the primary heater and a casing sustained by the bed-plate and closed at the top, sides, and one end, leaving one end only open for the projection of the iiame and wholly protecting the coil and primary heater from drafts.

Having thus set forth the nature of the invention, what is claimed herein is- 1. The starting-torch herein described, consisting of the base A, the casing attached to thelbase and closed at the sides, top and rear end, the vaporizing-coil having the inner coil b with the jet-aperture d upon one end opposite the center of the coil, the-outer coil b connected with the opposite end and encircling one end of the inner coil and extended backv aperture d opposite the center of the coil and the integral end of the tube extended in a straight line beyond the jet-aperture and provided with a screw-plugf to permit the cleansing of the tube at the jet, the opposite end of the coil having the outer coil b extended therefrom and continued in the feed-pipe a at the lower side of the inner coil b, and means for grasping the feed-pipe to support the coil, substantially as herein set forth.

3. The starting-torch herein described, consisting of the base A, the casing attached to the base, the vaporizing-coil having feed-pipe extended along the lower side of the coil, and fitted through the casing to support the coil, the wick-tube g supporting the wick below the feed-pipe and the coil, and connected by pipe and cock with a tank of combustible to form a continuously operating primary heater, and the casing constructed to wholly inclose the primary heater and the coil to protect them from drafts, and provided with airinlet holes for supplying the iiame.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

ROBERT J. MINER.
